A pre-existing condition is anything symptomatic, diagnosed, or noted in the record before the waiting period ends, usually a 6 to 12 month lookback. For Rottweilers, the common exclusions come from puppy-visit notes about hip laxity, intermittent lameness, or GI sensitivity. Curable conditions may re-cover after 6 to 12 symptom-free months.
Pre-existing conditions are among the most common reasons pet insurance claims get denied. For Rottweilers, this is the rule that determines whether hip dysplasia and elbow dysplasia are insurable at all. For Rottweilers, the rules are stricter than most owners expect, and the things that trigger an exclusion often look harmless in vet records.
A pre-existing condition is any condition that showed signs, symptoms, or a diagnosis before your policy's effective date, including the waiting period. Insurers don't need a confirmed diagnosis. A note in your vet records saying "mild intermittent right forelimb lameness, will monitor" is often enough for a carrier to exclude elbow and shoulder issues.
Most insurers review the past 12 to 24 months of vet records when you submit a claim. A few (Embrace, ASPCA) have curable-condition rules: if a condition resolves and shows no symptoms for 12 months, they'll start covering it again. Most others (Trupanion, Healthy Paws) generally treat documented history as excluded.
If your Rottweiler is young and healthy, enroll now. Compare the best pet insurance plans for Rottweilers and get coverage in place before any new vet record is created. The fewer vet visits in the past 24 months, the cleaner your record looks. If you have an older Rottweiler with some history, get quotes anyway, different carriers handle ambiguous notes differently. In the policy materials we reviewed, Embrace and ASPCA tended to be more flexible on pre-existing rulings, while Healthy Paws and Trupanion read as stricter, terms change, so confirm the current wording with each carrier.
Specific to Rottweilers and other large breeds: many insurers apply bilateral exclusions. If your dog tears the right ACL before enrollment, the left ACL is commonly excluded too, even though it's a different leg, it's considered the "same condition." The same logic applies to elbow dysplasia and hip dysplasia. Trupanion and Embrace are among the carriers more likely to cover the contralateral side; others have historically declined it. Check the bilateral wording in the sample policy before enrolling.

Generally, any condition that showed signs, symptoms, or a diagnosis before your policy's effective date, including the waiting period. A vet note like 'mild intermittent lameness, will monitor' is often enough for a carrier to exclude joint coverage going forward.
Most insurers review the past 12 to 24 months of vet records. A few (Embrace, ASPCA) have published terms that may re-cover certain curable conditions if the dog is symptom-free for 12 months; others, such as Trupanion and Healthy Paws, generally treat documented history as excluded. Confirm current wording with the carrier.
You can, but the new policy typically treats any diagnosed condition as pre-existing, even if your old policy was already paying claims for it. Switching after a major diagnosis usually loses coverage for that condition.
